PULLEY-FRAME.

Implication filed October 12,19044 Specification of Letters Patent.

To LLM tch-om, t may concern:

Be it known that we, .LAWRENCE ZAMBONI, residing at Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, and

Rossem. H. BOWEN, residing at Palmyra, in the county of Burlington andState of Nev,r Jersey, have invented certain new and useful Improvementsin Pulley-Frames, whereof the following is a specification,reference'being io had to the accompanying drawings. d

Our invention relates particularly to frames for Window-sash pulleys;and it is an object of our invention to provides frame of pressed sheetmetal which can 'be manufactured at less cost than the cast-metal framesheretofore employed.

Our invention includes a frame comprising a face-plate which is adaptedto be set in the window-jainb and to which is rigidly secured 2o apressed sheet-metal casinginclosing a pulle Y and supportin a shaft uponwhich the pu ley rotates. is hereinafter described, said faceplate maybe hollovi7 and comprise front and back members which areoppositelypressed pieces of sheet metal havin registered screw-sockets,the margins o' which are pressed or riveted to permanently connect saidtwo members, and said casing may be conveniently formed of two opositely- 3o pressed pieces of sheet metal providled with flanges whichare engaged between the front and back members of said facelate, saidback member of the face-plate an the casing members bein@ provided withinterengaging means to maintain them in rigid relation.

Our invention comprises the various novel features of construction andarrangement hereinafter more definitely specified.

In the drawings, Figure I is a front view of 4o a frame convenientlyembodyin our invention. Fig. II is a side 'view ofZ the frame, shown inFig. I partlv broken away. Fig. III is a rear view of said frame. Fig.IV is a transverse sectional view taken on the line IV IY in Fig. II.Fig.V is an elevation of the flanged edge of tlie casing member shown inFig. II and at the left-hand side of Fig. III. Fig. VI is a fragmentaryfront view of a modified forni of our invention. Fi VII is 5o a sideview of the device shown in Ivi VI. Fi VIII is a rear view of the devices own in igs. VI and VII. Fig. IX is a transverse sectional view takenon the line IX IX in Fig. VIII. Fig. X is a view similar to Fig. V, butshowing a unitary form of pulley-casing. In said ii ures the hollowfacevplate co1nprises the ront member 1 and the back member 2, which areboth formed of pressed sheet metal, the member 2 bein recessed andprovided with the periphera spacingflange 3, arranged to contactwitlithe lane member 1, as shown in Figs. I1 'an IV. Said front member 1is provided with countersunk pressed sockets 5, which register withcorrespondin sockets 6 in the back member 2 of the Iace-plate to receivethe heads of screws to conveniently secure the fa.ceplate in theWindoW-ja'mb, and said members 1 and 2 are secured in rigid relation bythe edges of the sockets 5, which are pressedl or riveted over the edgesof the sceltets 6, as best shown at the upper end of Fig. II. It may benoted that the hollow con struction above described is much more rigidthan if the front and back members of the face-plate Were in contactwith each other Without the interposition of the spacin -flange 3..

he, face-plate 1 contains the opening 8, through which the pulley 9propects, adjoining the sash Whose cord is to extend over said pulley,and the latter 1s mounted to rotate on the shouldered shaft 11 whichextends through the oppositcly-pressed sheetmetel members 13, which forma casing incosing said pulley. Said shouldered shaft 1 1 being providedwith rivet=lieads 16 on the outside of said casing members 13 securesthem in rigid relation, with their'opposite end iianges 18 in contact.Said casing members 13 extend rearwardl f through the opening 20 in theback face-plate 2, which opening is somewhat larger than the opening 8in the face-plate 1 with which it registers, and said casin members areprovided with the outward y-turned retaining-flanges 22, which are heldbetween the front and back facelates 1 and 2, asshown in Figs. II andIV. Said front and back members 1 and 2 maybe made of the same ordifferent metals-for instance, the plate 1 may be brass and theremainder of the frame steel. In either event we find it desirable toprovide means to secure the casing members 13 in rigid relation withsaid back member 2 independently of said front member lz and in the formof our invention shown in Figs. I to V, inclusive, the

rear face-plate 2 is provided with the flaps 23, l

which diverge from the plane of said member 2 when the casing membersare being inserted throu h the opening 20, but wluch are subseuent ypressed flat into engagement with t e recesses 25 in the opposite end ofsaid casing members 13, as s own m Fig. II, to interengage said caslngmembers 13 and plate 2.

Although we find it convenient to employ the interengaging flaps 23 andrecesses 25, above described, 1t is to be understood that other meansmay be provided upon the ca sing members and faceplate to maintaln themin rigid relation-for instance, ln the form of our invention shown inFigs. VI' to IX, inclusive. The front and rear faceplates 31 and 32 areprovided with registered Openings 33 and34, similarto the openmgsS and20 1n the faceplate above described, and the opposed casin members 35are provided eripheral anges 36, havlng lugs 39 exten ing throu h theopening 40 in the rear faceplate 32 en pressed to enlgage the latter asshown in VIII and X.

lthough we iin it convenient to form the (B8- Sing of oppositelyressedprimarily-sepa rate members 13, w ich are maintained in contact on thecenter line of the pulley 9, as described, the casin may be formed, asindi* cated in Fig. X, o a single piece of sheet metal 42 havi its ends43 in contact and com. rising the ange 44, which latter, like the. a es22, above described, is held between t e front and back members of thefaceplate.

We do not desire to limit ourselves to the precise details ofconstruction and arrangement herein set forth, as it is obvious thatvarious modifications4 may be made therein Without departing from theessential features of our invention.
